Rioting erupted in Kabul Friday when scores of Afghan men set fire to two US embassy vehicles after one collided with a civilian car killing a number of occupants, officials and witnesses said.

Television pictures showed the vehicles in flames and young Afghan men throwing stones at them.

NATO’s International Security Assistance Force (ISAF) said it had despatched a quick reaction force to the area, outside the American embassy and near US and Afghan army bases in the centre of the city.
